Hi Summer, 

Thank you for your interest in this project.

First of all GraphStream is not the easiest entry point to learn Java. 
Knowing Java is actually a prerequisite to GraphStream.

Also, keep in mind that this is an open source project that only exists 
thanks to people who give away time and energy for free. So, yes, some 
tutorials are probably very sparse (especially for a Java beginner) and lots 
of features are missing, but there is no point blaming anyone for this. 

For a step by step introduction to the library I advise you to follow this 
tutorial slides (the second tutorial, from slide 22, shows how to open a 
file...) : 

http://graphstream-project.org/gs-talk/tutorials.html

The code that goes along this tutorial can be downloaded from github here: 

https://github.com/graphstream/gs-talk  (the « Demos » folder can be imported 
as an Eclipse « maven project ») 

About your question on integer mapping rather than strings, you can access 
nodes with indices (graph.getNode(42)) but keep in ming that the order is not 
guarantied when nodes are added or removed.
